Question:

For the following functions, find the tangent line approximation of the two values and compare with the true value. Indicate which approximations are too high and which are too low. From graphs of the functions, try to explain what it is about the graph that causes this.
1. e0.1 and e-0.1.
2. ln(1.1) and ln(0.9).
3. 1.12 and 0.92.
4. √1.1 and √0.9.
